Increasing feedstock variability and regulatory requirements Refining & petrochemicals

In the fast-moving energy market, with constant demand and supply changes, refineries aim for maximum operational efficiency, productivity and lower production costs. The increasing variability of crude oil, high standards for equipment reliability and stringent environmental regulations pose challenges for refining and the petrochemical industry.

Climate change impacts on biomass feedstock Biomass

The generation of electricity by biomass conversion is driven by the transition towards renewable energy sources. In the process, challenges from the effects of climate change on feedstock availability, high investment and operating costs and large variability of plant-based feedstock as well as production emissions, process instabilities and lower conversion efficiencies must be tackled.

Refining & petrochemicals

Modern refinery for energy production

Remote NIR sensing in refining industry

In modern refineries, crude oil consisting of a complex mixture of hydrocarbons and heteroatomic organic compounds is converted into usable petroleum products. Using distillation units, crude oil is separated into gasoline, diesel, naphtha, liquefied petroleum gases, kerosene, fuel oil or bitumen. Naptha forms the feedstock for the petrochemical industry, which is important for the production of paints, varnishes, plastics, fibers, detergents and medicines, for example. VIS-NIR spectroscopy and chemometric methods are used for quality control in refinery and petrochemical plants. ZEISS PGS spectrometers (960 - 2500 nm) feature a robust and compact design and long-term stable calibration assuring process stability and safety. Remote, fiber-coupled sensing allows  for fast measurement of hydrocarbon mixtures, including octane, benzene, aromatics, olefins, color and turbidity.
ZEISS mono- & polychromator gratings can be used to detect fluid and gaseous contaminants in in-situ monitoring, even in high temperatures or harsh environments.
Raman spectroscopy is increasingly applied to measure specific liquid or gaseous contaminations. Raman spectrometers use blazed plane gratings with high efficiency and low stray light to enhance dynamic range.

Quality & process control of biomass conversion processes

Solid, liquid or gaseous biomass is an important renewable energy source. Processes like combustion, gasification, pyrolysis, fermentation, anaerobic digestion or pelleting create energy in the form of electricity, heat or bio-fuels. The main raw materials for biomass conversion are wood and agricultural residues, municipal waste or slurry. NIR spectroscopy is ideally suited for feedstock and final product quality control as well as process monitoring. ZEISS PGS NIR spectrometers (960 - 2500 nm) provide fast and cost-effective measurement of moisture, lignin, ash and dry matter.
